Upgrade ruby and remove the `therubyracer` gem causing libv8 conflicts
on MacOs.

`therubyracer` is an `execjs` engine to run JS, e.g. when building
assets. Assets are precompiled locally and copied by the Capistrano
tasks. So asset precompilation can fall back to the installed NodeJS
version.

This seems to have been used for the SWT lecture but is most likely not
working anymore.
